process_file_template: Do template expansion over a list of files.
process_file_template(source_list, template)
process_file_template applies a template list to a source file list,
returning the result of applying each template to each source. This is
typically used for computing output file names from input files.
The source_list is a list of file names.
The template can be a string or a list. If it is a list, multiple output
strings are generated for each input.
The following template substrings are used in the template arguments
and are replaced with the corresponding part of the input file name:
"{{source}}": The entire source name.
"{{source_name_part}}": The source name with no path or extension.
sources = [
myoutputs = process_file_template(
[ "$target_gen_dir/{{source_name_part}}.cc",
"$target_gen_dir/{{source_name_part}}.h" ])
The result in this case will be:
[ "/out/Debug/"
"/out/Debug/bar.h" ]
